: Q1. Is is possible to pass *analyzed* content to the
: public abstract class Signature {

No, analysis happens as the documents are being written to the lucene 
index, well after the UpdateProcessors have had a chance to interact with 
the values.

: Q2. Method calculate() is using concatenated fields from <str
: name="fields">name,features,cat</str>
: Is there any mechanism I could build  "field dependant signatures"?

At the moment the Signature API is fairly minimal, but it could definitley 
be improved by adding more methods (that have sensible defaults in the 
base class) that would give the impl more control over teh resulting 
signature ... we just beed people to propose good suggestions with example 
use cases.

: Is  idea to make two UpdadeProcessors and chain them OK? (Is ugly, but
: would work)

I don't know that what you describe is really intentional or not, but it 
should work
